ALARM-SIGNAL SYSTEM FOR AUTOMATIC WATERf-GAS-SFI'FCGN'PROLS' Annlicatiun tiled December 20, 1919. Serial No. 346.401.

To all ytrito/1t t may Concern MBe it known that l, Jeux Hin'nm TAUS- SrG,-a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a Vneu and useful .Harm-Signal System for Atutomatic "aterUas-Set Controls, of which the following is a specification.

Inmy Patent No. 1,119,472 of December 1st, 1914, there is shown and described an automatic Water gas set and that patent will serve to facilitate an understanding of the present invention, although the latter is not limited to the particular' automatic Water gas set described in that patent but is applieable to Water gas sets generally. In an automatic Water gas set there is a-n automatic control mechanism for openingl and closing the apparatus valves in certain groupsand at intervals called the blow and the ruin and such mechanism usually includes a master element Or elements` as a timer driven shaft, the movement of which acting through various kinds of relay apparatus effects the actual movement of the apparatus valves which are usually designated act-Ording to their functions. In the operation of av water gas set it is important that the apparatus valves should be opened and closed in the proper combination for effecting the run and the blo\\'," and at the proper intervals and without delay in operation of any of the. valves, but it is possible that automatic water gas sets, from some outside cause or another may on raro oweasious be caused to fail in one or more ol' these respects to funet-ion properly. This condition ol' atl'airs in practice results in the attendants wasting a considera-ble part of bis time, which might be usefully employed about the works, in watching the automatic Water gas set which, as a rule, functions properly and only needs a-ttentioiraiJ loup intervals.

The principal objects of the present in vention are, first, to give the tgras maker notice of the failure of any valve to function properly and to show which valve or valves, if any, has failed to operate properly; second, to enable the gas nuilicr or operator in charge oi an :iutouuilie water gas set to pen forni duties other than watching' il. with certainty that he will lu*` rzil'ud if' anythinpr goes wrong in lluautomatic operation and promptly advised just which valve or valves has gone Wrongjthild, to. show at all times and lnalconvenient place that the valves are operatmgjproperl `and arein lthe right rest positionsforftlie Or Afblow as the case may ,be,"but ivitli'ont giving an alarm` under conditionsfaaid vqlienthe ,valves are movingrom ,one restposition ito tlie other rest positlonin propercombiuations.

An explanation of 'the' invention may be facilitatedby a few general'statements involving reference to operation, followed by a more detail description of electric circuits. since they are Iemployed in the embodiment of the rinvention lshown on the drawings. In the drawings l and 2, are the synchronously time driven elements which, through apparatus not shown, respectivelyv position the apparatus valves in rest open or closed` positions for the run or for the blovrf The number of valves may vary but iu the case selected for thesake of description the apparatus valves are designated on Fig. l. ,as llot valve` Oil valve, Carb. blast. Steam valve. Stack valve, and (len. blast, and the parts so marked on the drawings ma)Y he assumed to be the cylinders which operate them, and the piston mds of these c linders muy he assumed to show by full 4on dotted lines the rest positions of the apparatus vulves whether open or closed. The full line positions of these piston rods correspond-to o blo\v" and the dotted line positions correspond to :1 run 3, generally arc lamps for indicating the rest positions` of the apparatus vali-'es for the blow and for the run,. und, us indi-cated in 1, thelower row of lamps is for indicalitioiiV during the blow and the next upper row of lamps is for indication during" th'mruii. The top row of lumps is for itlclicuting that the current is on the circuit onthult' the circuit is alive. There are circuit 'connections 'for connecting the p'iii'rloflcnips uppertaining to the valves in" sepggrte branches from one side or :ofthe-circuit und; these will be 'hereafter truoed' i :fire double pole double throniswit'chesfn u p propriete switch 4piroyrisitrnis.l rior: A' in;r either of the lomp bmchesltog v Itgp.- posite side or sign of the circuit to oppropriate lamps'or indicating the posi'- tion occupiedI by the valves; 15; is im'elhlm interposed in it local circuit 6, including en electric battery or source of energy?, it'lgiri'd switch S, :md two relu. 9 und 10, .errcpged when cle-energized to gse the circlt; sound, the alarm. There are connections, to be hereafter trncecl, for connecting the relays 9 and 10; in branches from one sido or sign of the circuit. Valve operated switch provisions, which may be partsof the switches 4, are arranged iuseries 1n ,the relay bronches for connectin one or the other of the 4relay branches to t e other side of the circuit when apparatus vulves are in opened or closed rest positions in desired s to silence thc iilnrm by breakin the oca circuit 6. by thus energizing 1e appropriate rclny. It :m3F of the apparatus valves fails to function properly und does not come to closed or open position as it should do in combination with thc other vai-Ives for u run or :i hlow," ,neither of the relays 9 uml l0. is cnerlrized und the local circuit 6` is closed :md the alarm is sounded. There is n circuit tube described forshunting the relays 9 and l0, to keep them closed and the alarm 5, silent during appropriate or intended movement of the apparatus valves, und this shunt circuit connection is controllccl h v carry-over mechanism 11 und 12. rcsponshfe to tlie elements 1 und 2, of the automatic control mechanism.

In Fig. G, the double polo (lollhlc throw switch 4. is noted upon through n link 1li, nml hy thc long nrm of in the Aarretngement o Fig. 5, is well adapted to the other apparet-.us valves. In Fig. 4, isV shown one ofthecarry over mech :inisms and it consists of u contact 19, which closes the circuit duringnn intenval of roto.- tiun of the com 1S, provided on the clement 2."

The wiring for the Carb blast lamps 3S und 39, in the particular instance illustrated in the drawings, di'ers from the wiring of most of the other pairs of lamps, but the difference does not change the prin riple and is due to Conditions of the par ticular layout. As a practical matter if the lamps 3S und 39, indicate a Wrong position ol the carhureter blast Valve, the indication is rorrect, but if the lumps 38 and 3), and the lamps of another valve malte such an iudilrzation, the meaning is the last mentioned rulre is out of time. The Circuit 80 9l. is provided with a snap switch S2, which is rlnswl when blowing with the rurluzrcler lilwl shul' oliM und in thul use this cirrui is a shuntwforfithe lefthnnd arm ofA the switch 4, of the Carb.iblast.valve.

In thespartieular j layout shown and during the' run the alarm is not responsiveV to thewr'Hotl valve down position nor to the oil on position, but this 'is a' matter of details in fthat=partieular layout. .Even Iiithe Hot valve is Vnot down during each run yor ifthe oil is notou during each run, no particular harm is done, hul. il' any one thinks otherwise` alarm connections can he applied to tlnl switches 4, of those vulves iu the manner fully described above` When the controllingr elements 1 and 2, are turning normally to position the apparatus valves for a run or a blow, it is desirable that the alarm remain silent. This is done by establishing a shunt circuit which keeps one or the other of the relays 9 and 10. energized and the energized relay keeps the loc-ul circuit broken and the alarm silent. The shunt circuit is from one side of the rirA ruit 28, hv lll), through one ol' the curry over devices ll or l2, by lll, to lead 100, which ronuerls h r lend HIL). with il. lhe other side of the circuit. .115,- is a shutdown switch and it is interposed in the circuit 1.16; and adapted to short circuit the entire equipment during the interval when EWatergate set is shut down.
